I used this a few times after purchasing it, but it kept running away, so I haven't used it much and am putting it up for sale. I've confirmed that it works. The only issue is that the top lid doesn't close quite right. Otherwise, there are no problems. Only the main unit is included, as shown in the photos. I will package it carefully to prevent water damage and ship it via anonymous, insured Mercari delivery, with shipping included. =================================== I also have other dog-related items for sale. If they can be shipped together, I will discount the shipping cost, so please take a look if you're interested. #MEOWペット ===================================
